The DIGITAL UNIX IPv6 team is pleased to announce the availability of the
latest IPv6 Early Adopters Kit (EAK) version X6.2 for DIGITAL UNIX V4.0D.

This kit is available for use and evaluation, but is not officially 
supported by Digital Equipment Corporation and is not recommended for use
in a production environment.

The following new features have been added for this release:

      - Configured IPv4 tunnel interfaces

	Configured IPv4 tunnels are now implemented as actual
	network interfaces.  The /usr/sbin/iptunnel command is
	used to create and delete tunnel interfaces.  Each
	configured tunnel is represented by an "ipt" device.

	RIPng over configured IPv4 tunnels is now supported.

	The IPv6 router daemon, ip6rtrd, sends Router Advertisements 
	over configured tunnels and responds to Router Solicitations
	received on a configured tunnel.

	The IPv6 host daemon, nd6hostd, performs router discovery
	and stateless address autoconfiguration in response to Router
	Advertisements received on a configured tunnel.

      - RSVP

	The EAK includes a Resource ReSerVation Protocol (RSVP)
	implementation and traffic control support for LAN interfaces
	(Ethernet, FDDI). See RSVP(7), rsvpd(8), iftcntl(8),
	rsvpstat(8), and the RAPI reference pages for more information. 

      - libc

	The EAK now includes libc.so, libc_r.so, libc.a and libc_r.a.
	The IPv6 API library routines have been incorporated into these
	libraries; you do not have to link against the libip6 library.

	The libip6 library is deprecated, and will be removed in a future 
	version of this kit.  Existing applications linked against libip6
	should be relinked against the IPv6 EAK libc.

      - ifconfig

	The ifconfig command now supports IPv6.  See the ifconfig(8)
	reference page for more information.

      - Reference pages

	Reference pages for many EAK components are now included in the
	documentation subset (IP6DOC123).

      - IPv4 over ATM

	Previous versions of this kit did not support IPv4 over ATM.
	IPv4 over ATM is now supported.

      - Stateless Address Autoconfiguration and Dynamic DNS Updates

	The IPv6 host daemon, nd6hostd, is now capable of dynamically
	updating the DNS during stateless address autoconfiguration.
	Refer to the DIGITAL UNIX Guide to IPv6 for details.

      - Compatibility with the old 48-bit interface tokens is no
	longer supported.

      - Compatibility with the old Solicited Node multicast address
	format (FF02:0:0:0:0:1:XXXX:XXXX) is no longer supported.
	

The IPv6 for DIGITAL UNIX kit supports the IPv6 base protocol and
addressing specifications, along with ICMPv6, Stateless Address
Autoconfiguration, Path  MTU Discovery, Neighbor Discovery, and RIPng.
It is capable of acting as a BIND server for AAAA records and of 
forwarding packets as a router.  This kit implements the IPv6 API 
specified in RFC2133.

There are a few limitations which should be pointed out:

      - This kit requires DIGITAL UNIX V4.0D with no patches.

      - Multi-processor (SMP) systems are not currently supported.

      - Some commands and utilities which are tightly integrated
	with kernel data structures might not work, or may yield
	unexpected output or behavior.

      - If you have a DIGITAL UNIX V4.0B system with an IPv6 EAK
	installed, and are planning to do an update installation 
	to DIGITAL UNIX V4.0D, you must delete the IPv6 EAK subsets
	before beginning the update installation.

	To find the IPv6 EAK subset names, use the following command:

		# setld -i | grep IP6

	To delete the IPv6 EAK subsets, use the following command:

		# setld -d IP6BASExxx IP6DOCxxx

	where "xxx" is the last three digits of the subset currently
	installed. 


The kit may be unpacked by issuing the following commands:

	# mkdir /usr/tmp/ip6kit
	Copy the compressed file to /usr/tmp/ip6kit
	# cd /usr/tmp/ip6kit
	# cat ipv6_binary_X6.2.tar.gz | gunzip | tar xvpf -

The kit contains two subsets:

	IP6BASE123 -- Contains the daemons, header files, utilities,
	libraries, and commands to support IPv6. 

	IP6DOC123 -- Contains the HTML and PostScript versions of the
	DIGITAL UNIX Guide to IPv6 and reference pages. 

DIGITAL recommends installing the documentation subset and reviewing 
the DIGITAL UNIX Guide to IPv6 prior to installing the base subset.
Install the documentation subset with the following command:

	# setld -l /usr/tmp/ip6kit IP6DOC123

Both postscript and HTML versions of the DIGITAL UNIX Guide to IPv6
are provided:

	file:/usr/share/doclib/ipv6/userguide/user_guide.ps
	file:/usr/share/doclib/ipv6/userguide/TITLE.HTM
  
Install the base subset with the following command:

	# setld -l /usr/tmp/ip6kit IP6BASE123

After installing the base subset, you must build and install a new 
kernel, and reboot the system:

	# doconfig -c SYSTEM_NAME
	# mv /vmunix /vmunix.save
	# cp /usr/sys/SYSTEMNAME/vmunix /vmunix
	# shutdown -r +5 "Completing DIGITAL UNIX IPv6 Installation..."

After booting the new kernel, configure IPv6 by running the IPv6
setup script:

	# /usr/sbin/ip6_setup

Refer to the DIGITAL UNIX Guide to IPv6 for detailed information
on installing and configuring IPv6.
